A link'ldhasjits ,npper endniounted upon the crossrod 8,

andjits lower end pivoted to an arm. or

lever extending from the hub 19 of the movable cams and preferably formed integr ttherewith. f I v Three or more cams are mounted upon the shaft 17, between the side frames of the bed? One of them 19, 1 is a fixed .caIn see'ured to the shaft 17, by a'set screw 17, or other smitahle means. The other cams 21 and 24', are preferably formedjintegral with the hub 19, which in; turn is secnred'to or formed intm-"agral ith a drum 15, around Whichis'inounteda brake band/14. Inqone end of the :brake bland 1ft, aj leveri 12, is ful} crumed, the lower end of which isfpivfoted to one end 01"- a link 18, and the opposite end of the link is pivoted to the other end of the brake band. The Opposite end of the lever 12, is pivoted to a link 11, which in. turn is pivoted or otherwise suitably secured, to the bed frame 2. r

In describing my mechanism, I have referred to the lower end of various levers, etc., and this reference is intended to apply to them when the bed is in its upright or vertical position as shown in Figures 1- and 2.

Steel cables 18, 20 and 23, are secured to the cams 19, 21 and 2 1, respectively, and pass over pulleys 22, 22 and 22 mounted upon a cross rod secured by the arms depending from the bed frame.

The opposite ends or the cables are respectively secured to springs 26, 27 and 28, adjustably secured to the base 1.

'Ihese springs may be set at any desired tension. In practice, I prefer to have the spring 28,01 the liXed cam 19, adjusted at suiiicient tension to counter balance the weight or the table empty or with a very light patient upon it, and the springs 26 and 27 adjusted at different tensions so that their force will ope'ate progressively upon the cams-21 and 2 1. These springs should be of sufficient size and force to counter balance the weight of the heavier patients, the intention being to arrange the springs in such a way as to counter balance the weight of all dii'l'erent classes or sizes ot patients that may be met with in ordinary practice so as to avoid the necessity of any great exertion in lifting the table to an upright position with the patient on it.

In the operation of my table, the bed is placed in its upright or vertical position as shown in Figure 2 and the patient is then required to stand upon the tread 9. His weight upon this tread carries down the supports 9, and the links 8, in turn forcing downward the link 10, turning the hub 19", upon the shaft 1'1, correspondingly. As the hub turns, it carries with it the movable cams 21 and as shown in dotted lines in Figure 2. These cams carry with them their respective cables and thus increase the tension upon the tension springs 26 and 27, until the tension c n1nter-balances the weight of the patient, the cam 19, remaining stationary until the bed itself is moved. After the patient is in proper position upon the tread, the upper end of the bed is lowered to a horizontal position. As the upper end of the bed descends, it carries upward the tread 9 but the lower end of the sup ports 9, being curved as shown at 9, and pa ssing through the yoke 25, forces the tread 9, into an oblique position as shown in Figure 8 and the weir; .t of the patient is transferred from the tread 9 to the bed 3, 5 and 2 3 or the table.

As the upper end of the table begins its descent, its frame 2, carries with it the link 11, thus applying pressure upon the long end of the lever 12, and tightening the brake band 14 upon the drum 15. The action of the brake band 1 1 in carrying the drum 15 with it also rotates the hub 19, thus carrying the cams '21 and 24-, with the hub and increasing the tension upon the correspond ing springs. I

It is obvious that'the size, torm, number and proportions of the various parts may be varied to suit the requirements of any particular case, that themethod of securing the revolution of the movable cams with the shaft may be varied, and that different forms of springs may be used or other well known forms of elastic resistance may be applied, without departing from the spirit of my invention.
